Cov nyhuv ntawm vulcanization rau ntawm cov qauv thiab cov khoom ntawm roj hmab

Cov nyhuv ntawm vulcanization rau cov qauv thiab cov khoom:

Hauv cov txheej txheem tsim cov khoom siv roj hmab, vulcanization yog cov kauj ruam kawg. Hauv cov txheej txheem no, cov roj hmab dhau los ntawm ntau yam tshuaj lom neeg sib xyaw, hloov los ntawm cov qauv linear mus rau lub cev zoo li tus qauv, poob qhov plasticity ntawm cov roj hmab sib xyaw thiab muaj qhov elasticity siab ntawm cov roj hmab sib txuas, yog li tau txais cov khoom siv lub cev thiab cov khoom siv kho tshuab zoo heev, tiv taus cua sov. Kev ua tau zoo, tiv taus cov kuab tshuaj thiab tiv taus corrosion txhim kho tus nqi siv thiab ntau yam kev siv ntawm cov khoom siv roj hmab.

Ua ntej vulcanization: cov qauv linear, kev sib cuam tshuam ntawm intermolecular los ntawm van der Waals force;

Cov Khoom: zoo plasticity, siab elongation, thiab solubility;

Thaum lub sijhawm vulcanization: lub molecule pib, thiab kev sib txuas tshuaj lom neeg tshwm sim;

Tom qab vulcanization: cov qauv network, intermolecular nrog cov tshuaj bonds;

Qauv:

(1) Kev sib txuas tshuaj lom neeg;

(2) Qhov chaw ntawm kev sib txuas ntawm cov khoom sib txuas;

(3) Qib ntawm kev sib txuas;

(4) Kev sib txuas;

Cov Khoom:

(1) Cov khoom siv kho tshuab (lub zog ntev tas mus li. Kev nyuaj. Lub zog tensile. Kev ntev. Kev ywj pheej);

(2) Cov khoom siv lub cev

(3) Kev ruaj khov tshuaj tom qab vulcanization;

Kev hloov pauv ntawm cov khoom ntawm roj hmab:

Siv cov roj hmab ntuj ua piv txwv, nrog rau kev nce qib ntawm vulcanization;

(1) Kev hloov pauv ntawm cov khoom siv kho tshuab (elasticity. Lub zog rhuav. Lub zog elongation. Lub zog rhuav. Hardness) nce (elongation. Compression set. Kev tsim cua sov qaug zog) txo qis

(2) Kev hloov pauv ntawm cov khoom siv lub cev, huab cua permeability thiab dej permeability txo qis, tsis tuaj yeem yaj, tsuas yog o, txhim kho kev tiv thaiv cua sov

(3) Kev hloov pauv ntawm kev ruaj khov tshuaj lom neeg

Kev ruaj khov tshuaj lom neeg ntxiv, yog vim li cas

a. Qhov kev sib txuas ua rau cov pab pawg lossis cov atoms uas muaj tshuaj lom neeg tsis muaj lawm, ua rau nws nyuaj rau qhov kev sib txuas laus mus ntxiv.

b. Cov qauv network cuam tshuam kev sib kis ntawm cov molecule qis, ua rau nws nyuaj rau cov roj hmab radicals kom sib kis

Kev Xaiv thiab Kev Txheeb Xyuas Cov Kev Mob Vulcanization Roj Hmab

1. Kev kub siab ntawm Vulcanization

(1) Yuav tsum siv lub zog nias thaum cov khoom siv roj hmab raug vulcanized. Lub hom phiaj yog rau:

a. Tiv thaiv cov roj hmab kom tsis txhob tsim cov npuas thiab txhim kho qhov compactness ntawm cov roj hmab;

b. Ua kom cov khoom siv roj hmab ntws thiab sau cov pwm kom ua cov khoom nrog cov qauv meej

c. Txhim kho qhov kev nplaum ntawm txhua txheej (txheej nplaum thiab txheej ntaub lossis txheej hlau, txheej ntaub thiab txheej ntaub) hauv cov khoom, thiab txhim kho cov khoom siv lub cev (xws li kev tiv taus flexural) ntawm vulcanizate.

(2) Feem ntau hais lus, kev xaiv ntawm lub zog vulcanization yuav tsum txiav txim siab raws li hom khoom, mis, plasticity thiab lwm yam.

(3) Hauv paus ntsiab lus, cov cai hauv qab no yuav tsum tau ua raws li: qhov plasticity loj, qhov siab yuav tsum me dua; cov khoom tuab, tus lej ntawm cov khaubncaws sab nraud povtseg, thiab cov qauv nyuaj yuav tsum loj dua; qhov siab ntawm cov khoom nyias nyias yuav tsum me dua, thiab txawm tias qhov siab ib txwm tuaj yeem siv tau

Muaj ntau txoj hauv kev ntawm vulcanization thiab pressurization:

(1) Lub twj tso kua mis hydraulic hloov lub siab mus rau pwm los ntawm lub tshuab vulcanizer tiaj tus, thiab tom qab ntawd hloov lub siab mus rau cov roj hmab sib xyaw los ntawm pwm.

(2) Ncaj qha nias los ntawm vulcanizing nruab nrab (xws li pa)

(3) Muab cua nias rau hauv

(4) Kev txhaj tshuaj los ntawm lub tshuab txhaj tshuaj

2. Qhov kub thiab txias ntawm Vulcanization thiab lub sijhawm kho

Qhov kub ntawm vulcanization yog qhov tseem ceeb tshaj plaws rau cov tshuaj tiv thaiv vulcanization. Qhov kub ntawm vulcanization tuaj yeem cuam tshuam ncaj qha rau qhov ceev ntawm vulcanization, qhov zoo ntawm cov khoom thiab cov txiaj ntsig kev lag luam ntawm lub tuam txhab. Qhov kub ntawm vulcanization siab, qhov ceev ntawm vulcanization ceev, thiab kev ua haujlwm ntau lawm siab; txwv tsis pub, qhov ua haujlwm ntau lawm qis.

Kev ua kom qhov kub ntawm vulcanization nce ntxiv tuaj yeem ua rau muaj teeb meem hauv qab no;

(1) Ua rau muaj kev tawg ntawm cov roj hmab molecular saw thiab vulcanization reversion, ua rau txo qis cov khoom siv kho tshuab ntawm cov roj hmab compound

(2) Txo lub zog ntawm cov ntaub hauv cov khoom siv roj hmab

(3) Lub sijhawm kub hnyiab ntawm cov roj hmab sib xyaw luv dua, lub sijhawm sau luv dua, thiab cov khoom tsis muaj kua nplaum.

(4) Vim tias cov khoom tuab yuav ua rau qhov sib txawv ntawm qhov kub thiab txias ntawm sab hauv thiab sab nraud ntawm cov khoom nce ntxiv, ua rau muaj kev sib xyaw tsis sib xws
